Definitions

  • the invention relates to a roll of material also called “ribbon roll” and supporting a thermoplastic ribbon of shallow cross-section and generally cross-wound on a hollow core, the ribbon being used for strapping.
  • Rolls of material in the form of lengths of string, bands, ribbons or the like that are made of textile fiber materials, mono-filaments or the like generally comprise a dimensionally stable hollow core and optionally a sleeve or a cuff circumferentially surrounding the outside of the fully wound material.
  • the hollow core consists of a cardboard tube made comparatively thick to assure stability, in particular also against the radial forces exerted by the wound material.
  • the hollow core-side end of the material to be wound on the hollow core is affixed by an adhesive strip to the hollow core, ie to its surface.
  • Cardboard hollow cores offer the advantage of being fairly economical. On the other hand they incur the drawback of being relatively heavy and foremost that they are significantly bulky, and consequently they entail some cost in shipping and storage. Another and significant drawback concerns their waste disposal because—as a rule—they will be wound with a useless remnant of material. Homogeneous recycling therefore requires to remove the material residues from the cardboard and to dispose separately of the two wastes.
  • thermoplastic strapping ribbons are made of polypropylene (PP) or of polyethylene (PE) which are both plastics of which the waste disposal is comparatively problem-free.
  • PP polypropylene
  • PE polyethylene
  • the German patent document U1 93 15 668 appropriately proposes that the roll of material be fitted with a hollow core (therein called inner muff) made of a strip of plastic, in particular PP.
  • the thickness of this plastic sheet is preferably 0.5 to 1 mm, especially 0.7 mm approximately.
  • the hollow core consists of a rigid-flexible strip of such a material with specially shaped end segments allowing to insert one strip end in the form of a tab at the other end of the cut-to-size piece into a slotted aperture in such manner that the cut ends of the cylindrical inner cylinder and so affixed to each other are fixed in place.
  • the object of the present invention is essentially to propose a substantially simplified roll of material relative to the state of the art.
  • the invention solves this problem by providing a plastic strip including an adhesive-coated sheet of which the adhesive fitted surface forms the outside of the hollow core facing the material.
  • the hollow core In the first place it is essential for the invention that it distance itself from the heretofore basic concept that the hollow core must be very rigid as a tubular body, for instance like a cardboard shell, or, as regards the inner hollow core of the German patent document U1 93 15 668, that it must be a rigid/flexible structure.
  • the invention is based on the insight that the wound material per se can impart high dimensional strength to the entire roll of material, especially when the surface of the material facing the hollow core is firmly bonded by its first winding layer to this hollow core.
  • the invention in surprising manner manages to make the hollow core from an adhesive coated sheet of a thermoplastic such as polypropylene (PP) or polyethylene (PE), the sheet constituting the hollow core being only 20-30 ⁇ thick.
  • PP polypropylene
  • PE polyethylene
  • a commercial pressure-sensitive adhesive film can be used as the sheet forming the hollow core.
  • a pressure sensitive film such as is used for packing tape may be used.
  • the invention is characterized by unusual simplicity of configuration, in particular as regards the hollow core.
  • the invention exploits the very nature of the ribbon of which the surface is usually made salient for reasons of strength.
  • the surfaces of the individual wound layers of the ribbon roll therefore lie frictionally against each other and the finished roll will not fall apart even when being moved/shipped horizontally.
  • the invention offers in this respect further strengthening by means of a sheet fitted on its side facing the material with an adhesive-coated plastic foil fitted with a projecting, adhesive-free or adhesive-neutralized tear-open tab external to and taut around the material like a sleeve.
  • the invention concerns a simple method to produce a roll of material of the cited kind.
  • This method is characterized by the following steps:
  • an adhesive-coated strip of foil is wound by its surface opposite the adhesive-coated outer surface around a substantially circular-cylindrical support mandril,
  • the support mandril is set in rotation about its longitudinal axis until the roll of material has reached the desired quantity of material
  • step (e) The roll of material is removed from the support mandril, and optionally another step (f) may be carried out before or after step (e), namely
  • this invention proposes a device with which to carry out the above method and is characterized in that this device includes a support mandril in the form of an expansion mandril composed of segments which are substantially adjustable radially to axis of rotation and which following preparation of the roll of material can be retracted to decrease the mandril diameter to allow withdrawing the roll of material from the expansion mandril.
  • FIG. 1 is a perspective of a finished roll of material
  • FIG. 2 shows a roll of material when beginning to wind material onto the hollow core
  • FIG. 3 is a schematic side view of the hollow core being supported on an expansion mandrill
  • FIG. 4 shows an alternative embodiment of tear-open tab 14 in FIG. 1 .
  • FIG. 1 shows a finished roll of material denoted by 10 .
  • This roll consists of a hollow core 11 , the material 12 wound thereon and of a plastic foil 13 surrounding the outside of the wound material 12 in the manner of a sleeve and fitted with a terminal tear-open tab 14 .
  • the hollow core 11 consists of a foil of a cylindrically wound plastic strip fitted with an adhesive coated outer surface 11 a .
  • the outer plastic foil 13 also is adhesive-coated on its inside 13 a .
  • the tear-open tab 14 comprises either no adhesive coating is illustratively neutralized by a terminal segment 131 of the plastic foil 13 being folded into two plies 132 , 133 to form the tear-open tab 14 so that the plastic surface bond to each other.
  • the significant mechanical strength of the roll of material 10 of FIG. 1 results on one hand from the first winding layer of the material 12 close to the hollow core being firmly bonded to the hollow core. Another improvement in strength is implemented by tautly enveloping the finished material 12 with the plastic strip 13 . Even when resting on its circular-cylindrical surface, and possibly when being shaken during shipping, such a roll is strong enough not to incur shape degradation.
  • FIG. 2 diagrammatically shows the plastic foil 16 which is adhesive-coated on the outside 16 a and which was wound to form the hollow core 11 .
  • the overlapping terminal segments are omitted from FIG. 2, however FIG. 3, discussed further below, does diagrammatically show the overlap zone denoted by 17 .
  • the first winding ply 18 of a material 12 is deposited directly on the adhesive surface 16 a .
  • winding began at the center of the hollow core and terminates first on the left side as seen in FIG. 2, whereas the next winding is carried out as far as the right end of the hollow core (this is the so-called cross-winding).
  • the first half of the first winding ply and the second half of the second winding ply thus form the ply of material coming into contact with the layer of adhesive.
  • winding is carried out to completion and at relatively low tension, ie winding stress, in order to preclude that the wound material undergo inadmissible warping.
  • An expansion mandril 19 which in the embodiment of FIG. 3 comprises four segments 20 substantially adjustable in the radial direction is used to wind the unstable plastic foil 16 into the hollow core 11 .
  • the pressure-sensitive foil 16 is wound with its adhesive side 16 a facing outward around the outer surfaces of the expanded segments describing approximately a circular cylinder, the mutually touching foil ends being bonded together in the overlap zone 17 .
  • the winding procedure described in relation to FIG. 2 may be initiated and after its termination the segments 20 can be retracted toward the center of the expansible mandril 19 to allow easily removing the finished roll of material from the winding device, or it may be subsequently enclosed with the outer sleeve 13 discussed in relation to FIG. 1 .
